Hello all....
I have a 87 Chevy R10 with a 4.3V6 and 400 trans. I am putting in a 383 with a rebuilt 400. Can anyone tell me the location of the kickdown switch on this year truck? I have never worked with a 400 before and not sure what the switch looks like. I am not sure if it is still there.

Any help is appreciated.

There isn't one. The TBI trucks controlled the TH400 kickdown from the ECU by reading the throttle position sensor. I assume you're dumping the computer so you'll need to rig a kickdown switch from an earlier TH400 truck. Any 1986-earlier full size pickup with TH400 should have the switch on the accelerator pedal.

thanks for the confirmation on computer and yes no computer. Any one have some photos of the switch on the pedal so Iknow what I am looking for in the junkyard?

The switch looks like this, though the truck bracket may be different. Just look at the accelerator pedal where it bolts to the firewall under the dash. The switch will be right above the pedal. Any 1986-earlier truck with a TH400 will have one.

With just a little fabrication ... you can have a neat, functional 400 kick down switch.

This is the one on my 32 Ford roadster. There is not enough room in/around the firewall/floorboard area for a foot operated switch. The older Chevrolets and Buick used a accelerator activated switch so I just made a little bracket and fixed a small switch to work on the 400 Turbo in my 32 Ford/with SBC.

Of course that's a viable option, but I'm lazy and with no fabrication one can bolt on factory parts for a C/K truck.

True, so true ...

But maybe not everyone looking at this thread has a C/K truck.
A LOT of vehicles just do not have the room for a factory type C/K switch.
Most early street rods ... do not.
I also realize that most early street rods have gone to using the automatic overdrive transmissions ...
not the older Turbo 400's. I have the 700R4 in my 32 3W.

Anyone out there have a installed gas pedal installation? Looking for all the options.

I am thinking a small modification to a old bracket I have could work on the carb realitvely easy.
Does the pull chord need to attach to the same place the throttle cable goes? I am running a Jegs billet throttle linkage setup were the stock throttle cable attaches. I am thinking I can mount a braket below this and run the spring up to the point on the carb.
